upper ends of the needles and in line therevrith. ward, It will be understood that the narrowing lpoint carrier at the left end of the needle row has no stud to contact with the picot bar mechamsm and hence does not participate in the operation of the picot bar lengthwise. It will be observed from Figure 1 that the carriers 44a for the narrowing points occupy positions out beyond the ends of the picot bar and hence out beyond the positions ordinarily occupied by these carriers when they are ready to eifect the narrowing of the fabric. These extreme outward positionsy are assumed by the narrowing point carrier by the operation of the hand crank 44j, which is used to reset the narrowing points, after a stocking is nished,into position for making the next stocking, only in this present form of machine, involving the picot mechanism, the narrowing point blocks are set farther outwardly than when the narrowing points are to do only narrowing.

vThese extreme outward positions o f the narrowand we have here particular reference to the leftward movement of the right hand narrowing point carrier, is due to the step by step rotary movement of the screw shaft 44h derived through the gears 44e, 44d, on shaft 44x, pawl and ratchet 44f,e44g, drum 44', band 44e, lever 43g and cam 4311. on the main cam shaft a and it will be understood that for narrowing this leftward movement of the narrowing point carrier is of a length equal to two needles, but when the movement of the narrowing pointcarrier is utilized for the automatic operation of the picot bar it will be understood that the movement of said narrowing point carrier must be limited to only one needle space. For deriving this limited movement through the Vsame pawl and ratchet mechanism above described which, for narrowing, gives the movement equal to two needle spaces, a shield 11 is employed so that the pawl 44j in its regular reciprocating movements will turn the ratchet 44g only one tooth instead of two teeth and this limited movement of the ratchet will result in a leftward movement of the right hand narrowing pointcarrier .44a to the distance of one needle toactth shield is heldin its effective position q to prevent the pawl 44j from taking more than iro space instead of two as ordinarily used in narrowing. Contact of this pin with the adjusted shield will hold the pawlfrom engaging the ratchet during the initial movement of said pawi.

This shield 11 is mounted loosely on the shaft of the ratchet and has its edge 11a in the path of apin 12 onthepawl.v

. Whenl the picot bar is in lowered position ready 'one tooth by anarm' 13 having a pin 14 engaging anotchinthebodyoftheshield. This arm 13 is fixed to a rock shaft 15 Journailed in the fashmaar frame'.-said rock Shenyang under tensiq'n of a spring 16 whichmoves'the shield into eifective position to make the pawl take only one tooth. This action takes place when the picot -tar is v'me 'when the picot bar is in its raised or idle position down in position. v

said rockshaft` 15 hasan arm 17 which will be operated bythe bracket 17a on the rock 'shaftzwhich carricsthepicot barsothat the shield controlling rock'shaft 15 will be turned operate the ratchet, the space of two teeth for regular narrowing operations. In other words this same pawl and ratchet mechanism serves both during the making of picot and during narrowing, but it is varied in its action so that for making picot it moves the narrowing point carrier and hence the picot bar one needle space leftward, Fig. 1, whilefor narrowing it will move the narrowing point carrier two needle spaces towards the middle of the needle row.

As before stated any desired number of picot courses may be formed and for this purpose the narrowing point carrier 44a is moved -back and forth i. e. leftward and rightward so that the picot bar will be reciprocateci the distance of one needle space, the leftward movement of the bar being due to the pushing action thereon of the right hand narrowing point carrier, and the right hand movement being due to the follow up action of the spring 5 when the narrowing point carrier moves outwardly the distance of one needle space. This outward or return movement of the narrowing point carrier is due to the pawl 46 and ratchet 45 giving a retrograde movement to the screw shaft each time the fashioning frame 47 moves down and up. This action is similar to that which is performed when fashioning the heel tabs, said pawl 46 having been set to engage the ratchet 45 for this retrograde action of the screw shaft. This pawl 46 is pivoted to the side frame of the machine at 46a and it is urged towards the ratchet by the spring 46a.

In the present form of the machine involving the picot mechanism-there is mounted on the rear of the frame bar 46p, Fig. 5 which extends across the fashioning frame 47 a rook shaft 18 to control the position of the pawl 46 inrelation to the ratchet 45. The pawl 46 is slotted lengthwise as at 46a. It receives in its slot a pin 46c from an arm 46d on a short rock shaft 46e which is mounted in one of the links 46j which operate the fashioning frame 47 vertically. This rock shaft has onits inner end a depending arm 46g provided with a pin 19 engaged by the notched end (see dotted lines Fig. 10) of a latch 20 attached to one end of the rock shaft 18 at the back of the said frame bar 46p. Said rock shaft is under tension of a coil spring 22 tending to keep the notched end of the latch down on the pin to hold the short rock shaft which is mounted in the link againstthe tension of the spring 46g of pawl fashioning. frame. When, however, the machine is set for making picot a cam or member 1b on the-carrier block 44a of the'narrowing points and turn the same slightly so as to lift the latch will act against a block 23 on the rock shaft, 18

20 from pin 19 of arm 46g whereupon the rock shaft 46e mounted in the link 46! will no longer hold the pawl 46 back against the tension of its spring 46g' but on the contrary the pawl 46 under the action of its spring will move into the rangeof bodily movement of the ratchet-45 upwardly `with the fashioning frame 4'1 so that the screw shaft 44h will be turned backwardly to retract the narrowing point carrier outwardly. The picotv bar under thepressure of the spring 5 will follow this rightward or outward movementl of the right hand narrowing point carrier 44a andwill thus assume position for beginning the formation of the next picot course.

The block 1b of the point carrier 44a has bevelled ends 1b and block 23 has bevelled corners 5 23h to permit a camming action of block 1b thereon,

The rock shaft 18 at the back of the cross bar 46p has a second block 23a thereon near its inner end, the purpose of which is to control the pawl 46 in a manner above described so that when the narrowing point carriers are set inwardly along the `screw shaft 4417 to their positions for narrowing the heel tabs the right hand narrowing point carrier will vcome against this inner block and the pawl 46 thereby will be set in position to perform the retrograde movement o'f thev screw shaft for moving the transfer points one needle space outwardly, it being understood that at this time the inward movement of the narrowing point carrier is two needle spaces instead of one.

The block 23a has a bevelled corner 23a' to receive a camming action from shoulder 1b' of the block 1b, Fig. 4.

After the picot has been formed the narrowing points must be moved from their outward positions above described beyond the ends of the picot bar inwardly into position for narrowing'. At the termination of the picot formation the main cam shaft which had been shogged to the right for bringing the cam 43h intoline with the roller of lever 43g is restored to its position at the left for knitting. This action throws the cam out of line with the said roller and in order that the narrowing point carriers may be automatically set inwardly along the screw shaft 44h into position for narrowing it is necessary to again bring the roller of lever 43g and cam 43h into operative relation. 'I'his is done by shifting the roller into line with the cam. For this purpose a cam 24 is mounted on the yarn changenshaft b.' This cam has a projection 25 on its side face which operates an arm 26 on a rock shaft 27 mounted on the outer side of the right hand frame or standard of the machine.

` This rock shaft has a dependingarm 28 which shifts laterally an arm 29 mounted on a pivot pin 30, which arm in turn shifts the roller of lever 43g into line with the cam 43h so that said l lever 43g will be operated and through the connections involving the band. 44e and pawl and ratchetfmechanism the screw shaft 44h will be turned step by step to move the narrowing point carriers inwardly from their outward positions beyond the ends of the picot bar to their positions for narrowing. In this movement the picot bar will be moved leftward and the clutch 6, 7 n will be released by separating the clutch collar 6 from the fixed clutch member 7 and-then the spring 5 will turn the rock shaft .2 and raise the 60 picot bar' to its upper or idle position. At the same time the rock shaft which controls the position of the'shield 11 will'be released by the departure ofthe picot bar from operative position and the springl of said rock shaft will turn the same to withdraw the shield so that ...then at each feeding movement of the pawl 44j the narrowing points will be set inwardly of the machine two4 needle spaces as in regular narrowing actions. Pivot pin' 30 is pressed outwardly 70 by spring`30a, Fig. 1V.

' The cam 24 on the yarn changer shaft has a. peripheral projection 24d which'will restore the pawl 46 to inactive position against the pressure n of its spring so that the latch can resume operative position to hold said'pawl out of thepath of the ratchet 45 as the same moves up and down with the fashioning frame 47. The connection for doing this includes a lever 31, Fig. 6, pivoted to the machine frame and having a spring pin 32 to be set or pressed upon by the peripheral projection 24d on the said cam 24. This lever is connected by a link 33 with the pawl 46. The hook of the pawl 46 and the relation of the teeth of the ratchet thereto is such that although the connections are set by the action of the cam under pressure by reason of the employment of the spring pin, said connections will not be able to move the detent to inactive position until, in the downward movement of the fashioning frame, the engaged tooth of ratchet 45 will leave the hook of the detent 46 so as to release the same whereupon the reaction of the spring pressed pin 32 will push the link 33 leftward and return the pawl 46 to inactive position.

In its idle position the picot bar will be retained by a catch 34 engaging a block 34a xed on the rock shaft 2. The bar will remain in this position until the machine after completing a stocking is reset for the next stocking, whereupon the catch will be released by hand and the bar will be swung down by hand into position for making picot.

This resetting action for making a new stocking involves operating the hand cranks 44j and 437' to respectively restore the narrowing points to inactive position and to restore the yarn carrier stops to their normal positions, also the picot bar isswung down by hand where it is locked by the clutch 6, 7.

The lever 43g operates two bands, 44e for moving the narrowing point carrier for vmaking picot or for narrowing, and 43e for automatically adjusting the yarn carrier stops as in said application 590,942. These stops are not intended to be operated during the time that the picot is being formed, hence means are provided by which the operation of the band 43e is rendered ineffective during picot formation. For this purpose the cam 24 on the yarn change shaft is provided with a second peripheral cam 24h which at the proper time operates the bell crank lever, 35 pivoted at 36' to the vframe bracket so that it will lift and render inactive the Vpawl 43k pivoted on the side of the loosely mounted drum 43:1: Fig. 3 on stub shaft of crank 437' operated by band 43e. This pawl 43k when allowed to be eifective operates the ratchet km and gearing ko for turning screwshaft 43 so that when this pawl is rendered inactive said screw shaft will not be operated and the yarn carrier stop mechanism will remain unaltered as to the disposition of its stops during picot formation. The cam 24h is of such length that it will maintain the pawl 43k out of operation and therefore the yarn carrier stops are at rest until the narrowing points have been restored from their so called idle positions beyond'the ends of the picot bar,-inwardly into position ready for normal narrowing operations. That is to say, during the time that the projection 25'on the cam 24 is acting on lever 26 and holding the shifting roller in line `with the cam 43h for the movement of the narrowing points inwardly the cam 24h remains in action against lever 35 and the pawl 43k isnthus held out of operation with the carrier stops at rest.

The yarn carrier stops are mounted on brackets 36 which latter are adjusted by the screw shaft 43. In Figs. 1 and'2 the cam 47a is for operating the connections 4'717,` 47e, 47d and 46j which work the fashioning frame 47 during both picot and narrowing formation. At 50, 51 are shown parts of the shog'ging cam for the main cam shaft.

A guard is arranged at A to protect the picot points when raised to idle position.

The yarn change shaft has thereon cam means such as illustrated generallyat 40, Fig. 14, for operating selector slides indicated generally at C1, C3, Cfligs. 13 and 14, which provide abut'- ments to be set selectivelyl in line with slides 317 mounted on a driver block 3l which is reciprocated by an endless'band 30 to which the driver block is secured. This band is reciprocated by a connector extending from the slur' cock carrier, as in the application above referred to. The

reciprocating driver block 31 carries pawls 31a which, when raised by the cam portions 31h. of the slide 311i, will engage the dogs 34 on endless bands 26 which carry the yarn guides. These yarn guide bands are arrested at` the ends `of their prescribed lengths of strokes by stops Rs carried by the blocks 36 which are adjusted by the-screw shaft 43. The stops are controlled to be set into or out of line with the projections 35 of the dogs 34 by levers 36e mounted on the blocks 36 and controlled by cam' means on the yarn changer shaft b.

'I'he pawls 31a have frictional engagement with their respective dogs 34, there being one of these for each endless yarn guide .carrier band, and when any one of the said carrier bands is arrested by its dog coming against its stop Rs, the pawl will recede downwardly owing to the inclines at 34d,34c, o'n thedogs,'and the inclined shoulders 31h on the pawls, and thus the driver will pass on to the end of its stroke.

' -In arriving at the end of its stroke, the appropriete selector slides C1, C3, C5 will have been set by the appropriate cam on the yarn change shaft so that the abutment on this slide will operate the appropriate one of the cam slides 317' on the driver block 31, and this will lift the corresponding one of the set of pawls 31a so that this will operate, on the reverse stroke of the ldriver block, that one of the yarn carrier bands which the selective action of theA cam on the yarn changer shaft` inaugurates and consummates through the setting ofthe prescribed selector slide and the operation thereby of the describedl Darts on the driver block 31. v
